Detailed ways

Shown with reference to Fig. 2 to Fig. 8, it has shown the specific structure of various preferred embodiments of the present utility model; It comprises pipe material main body 100, and this pipe material main body 100 inside forms non-circular special-shaped hole, so, with Obtain better shock absorption effect and higher structural strength; the shape of the special-shaped hole is not limited, for example, the special-shaped hole shown in Figure 2, Figure 5 and Figure 7 (numbers 201, 202, 203 in the figure) or other shapes can be used .

Specifically, it can be realized in two ways. Here, the first embodiment is used for illustration. As shown in FIG. 40 is installed in the fiber capillary 30, certainly this expansion powder 40 is rolled into fiber capillary 30 after wrapping by plastic film 50, and this plastic film 50 can be nylon material etc., to prevent expansion powder from penetrating; , select the outer peripheral special-shaped mold 200, as shown in Figure 3, adopt a square special-shaped mold, place a number of thin fiber tubes 30 on the special-shaped side of the special-shaped mold 200 (the number can be selected according to needs), and then wind and roll outside to form the aforementioned The fiber outer tube 10 is put into the mold cavity of the mold to heat and harden together, the expansion powder is heated and expanded and extruded, the fiber outer tube 10 is shaped in the mold cavity, and the expansion of the fiber thin tube 30 is pushed against the special-shaped edge of the special-shaped mold 200 The inner wall surface of the pipe body 100 is formed on top, and finally the special-shaped mold 200 is pulled out to form the special-shaped hole 201, so that the special-shaped hole 201 is formed by the outer wall of the fiber capillary 30. As shown in Fig. 5, Fig. 6 and Fig. 7, Fig. 8, two kinds of special-shaped hole forming modes are the same as those mentioned above. They all utilize the same outer peripheral special-shaped mold 200 as the special-shaped hole 202, 203 for processing, and place some fibers at the position of the special-shaped edge. The capillary 30 can be completed by wrapping the fiber outer tube 10 externally, which will not be described in detail here.

As shown in Figure 4, it has shown the second kind of implementation of the first embodiment, also selects the special-shaped mold 200 identical with special-shaped hole shape, and it comprises the fiber outer tube 10 that is rolled by fiber layer and the fiber inner tube When making the tube 20, first wrap the fiber inner tube 20 on the special-shaped mold 200, and then install the expansion powder 30. Of course, in order to prevent the expansion powder 30 from penetrating, it can be covered with a plastic film 50, and then wrap the fiber outer tube 10 on the outer surface , the fiber inner tube 20 is embedded in the fiber outer tube 10, the aforementioned expansion powder 40 is sandwiched between the outer wall of the fiber inner tube 20 and the inner wall of the fiber outer tube 10, and finally put into the mold cavity of the mold for heating and shaping to make the expansion The powder 30 squeezes the fiber inner tube 20 and the fiber outer tube 10 respectively, and the fiber inner tube 20 is squeezed to the outer surface of the special-shaped mold 200, and then the special-shaped mold 200 is pulled out to form the special-shaped hole 201 of the aforementioned pipe body 100, In this way, the shaped hole 201 is formed by the tube wall of the fiber inner tube 20 .

The applicant has repeatedly analyzed, tested and tested that the racket made of the fiber pipe with special-shaped holes of the utility model has a better shock absorption effect, and its structural strength is obviously enhanced.
